DETAILED DESCRIPTION

The present disclosure generally provides a remote control deviceincluding a control unit and one or more holders for the control unit.The control unit may form a stand-alone electronic module or unit thatincorporates all of the functions and components needed to operate orcontrol the operation of an electronic device. In some embodiments, thecontrol unit includes a power supply (such as one or more batteries), acommunication circuit (such as a receiving circuit, a transmissioncircuit, or both) for communicating with the electronic device (such asby radio waves, infrared, or other suitable transmission methods), auser interface (such as an electronic display, one or more depressiblebuttons, or both), and a body for housing at least some of thecomponents of the control unit.

The control unit and the one or more holders may be separate, distinctcomponents. The control unit may be interchangeably seated in variousdifferent holders. The holders may differ from one another in variousaspects, such as aesthetics and/or function. In some embodiments, one ormore holders are configured to support the control unit on asubstantially horizontal support surface, such as a countertop, atabletop, a floor, or the like. In some embodiments, one or more holdersare configured to attach or secure the control unit to a substantiallyvertical support surface, such as a wall. A single control unit may beremovably received within an assortment of different holders.

The holders may each include a body defining a cavity or recess thatopens through a surface of the body. The body may include one or moreinternal side walls and an internal end wall defining the cavity. Insome embodiments, the internal end wall projects inwardly from the oneor more internal side walls and defines a closed bottom of the cavitysuch that the cavity includes a closed end associated with a rear sideof the holder and an open end associated with a front side of theholder. In some embodiments, the internal end wall projects inwardlyfrom the one or more internal side walls and defines an open bottom ofthe cavity. In these embodiments, the cavity is formed as a through-holeextending through the holder, and the internal end wall functions as anabutment wall for the control unit.

When seated in a holder, the control unit may be recessed into theholder to protect the control unit, particularly the front face of thecontrol unit, from damage or inadvertent activation regardless of theorientation of the holder. For example, a user may place the holderupside down to conceal the control unit from view without damaging oractivating the control unit. The holder may surround the side surfacesof the control unit such that the control unit is concealed when viewingthe remote control device from the side. In some embodiments, the holderalso encloses a rear surface of the control unit such that only a frontsurface of the control unit is accessible when the control unit isseated in the holder. In some embodiments, the holder is configured tobe supported face down to hide the working surface of the control unit,and the remote control device may blend into its environment and appearto be an ornamental object, rather than a remote control device.

The recessed nature of the control unit may make it difficult to removethe control unit from the holder. The control unit, the holder, or bothmay include one or more access, removal, or surface features tofacilitate removal of the control unit from the holder. In someembodiments, the holder includes a recessed area that extends at leastpartially along a perimeter or other portion of the control unit toenable a user to engage the control unit and remove the control unitfrom the holder. In some embodiments, the control unit may include asurface feature, such as a protrusion or recess, associated with aperimeter of the control unit to assist in removing the control unitfrom the holder. The surface feature of the control unit may beaccessible via the recessed area of the holder when the control unit isseated in the holder.

The recessed area of the holder may surround the cavity defined in theholder. The recessed area may include a first portion that surrounds thecontrol unit and a second portion formed in the first portion. The firstportion may be formed by a chamfered or other suitable surfacesurrounding the cavity of the holder. The second portion may extendrearwardly from the first portion toward the internal end wall of theholder to provide additional access to a portion of the control unit,such as a side wall of the control unit. When the control unit is seatedin the holder, the surface feature of the control unit may correspond tothe second portion of the recessed area of the holder to facilitateremoval of the control unit from the holder.

Referring to FIGS. 1-3, a remote control device 100 may include acontrol unit 102 and a holder or support 104. The control unit 102 maybe removably seated in the holder 104. When seated in the holder 104,the control unit 102 may be surrounded on its side and rear surfaces bythe holder 104. In some embodiments, the holder 104 defines a cavity 106that opens through a front surface 108 of the holder 104, and thecontrol unit 102 is removably seated in the cavity 106. The control unit102, including its user interface 110, may be recessed relative to thefront surface 108 of the holder 104 when seated in the cavity 106 (seeFIGS. 1-3, 14, and 15). The recessed nature of the control unit 102relative to the holder 104 may enable a user to position the remotecontrol device 100 in any orientation, such as upside down, on a supportsurface without damaging or inadvertently engaging the control unit 102or user interface 110.

Recessing the control unit 102 relative to the holder 104 may provide auser with many aesthetic options. For example, when the remote controldevice 100 is oriented upside-down, the holder 104 may conceal thecontrol unit 102 from view such that the control unit 102 does notdetract from the aesthetics or decor of the associated room. In thisupside-down orientation, the exterior shape or configuration of theholder 104 is visible to the user, and different holders may be formedin different exterior shapes or configurations to suit the aestheticpreferences of the user. In some embodiments, the front surface 108 ofthe holder 104 defines a rim 112 that extends forwardly of the userinterface 110 of the control unit 102. When the holder 104 is positionedupside down, the rim 112 may abut against a support surface, therebyoffsetting the user interface 110 from the support surface to protectthe user interface 110 from damage, inadvertent activation, or both.

The holder 104 may be formed in various configurations to provide theuser with many aesthetic options. In some embodiments, an assortment ofholders 104 are provided with various shapes, such as a triangular shapewith rounded edges, a cylindrical or ring shape, or other asymmetricalor symmetrical shapes, to provide the user with many aesthetic options.In some embodiments, an assortment of holders 104 are provided that areconstructed from various materials, including metallic and/ornon-metallic materials, which may be man-made or natural. In someembodiments, an assortment of holders 104 are formed of a polymericmaterial, such as acrylonitrile butadiene styrene (ABS) or Surlyn (acopolymer of ethylene and methacrylic acid), some of which may be plated(e.g., with a vacuum metallized nickel plating). In some embodiments, anassortment of holders 104 are provided with different finishes, such asa MT-11005 surface texture, a brushed texture (e.g., a concentrichairline brush), a polish (e.g., a 6000-grit ultra-fine polish), acoating (e.g., a matte spray coating), or other suitable textures foraesthetic and/or functional purposes. In some embodiments, an assortmentof holders 104 are provided with different colors, such as black, white,gray, silver, blue, red, yellow, or other colors to provide the userwith many aesthetic options.

Although primarily ornamental, the exterior shape of the holder 104 mayprovide an ergonomic benefit. In some embodiments, the exterior shape ofthe holder 104 may facilitate single-handed use of the remote controldevice 100 by a user, and/or enhance the aesthetic aspect of the holder104 when not in use. Referring to FIGS. 1-3 and 8, the holder 104 isdepicted as a laterally-extending body (in the plane of FIG. 1) having afront surface 108 and a rear surface 120, with a depth defined (in theplane of FIG. 2) between corresponding points of the front and rearsurfaces 108, 120. The front surface 108 may include a linear or planarportion or rim 112 and a continuously curved portion extendingrearwardly from the rim 112. The rear surface 120 may define acontinuously curved portion. An outer perimeter edge 105 may be formedat the intersection of the continuously curved portions of the front andrear surfaces 108, 120, and may define a generally triangular shape withrounded vertices 107 a, 107 b, 107 c. An external side wall of theholder 104 may be defined by side portions of the front and rearsurfaces 108, 120 of the holder 104 (see FIG. 2), and may be defined asa continuous curve extending around the perimeter edge 105.

The triangularly-shaped holder 104 may comfortably fit in the palm ofthe user's hand for either right-handed or left-handed use, therebyfacilitating one-handed use of the remote control device 100. Forinstance, with reference to FIG. 1, when held in a user's right hand,the vertex 107 b may be adjacent the user's thumb, the vertex 107 a maybe adjacent the user's forefinger, and the vertex 107 c may be adjacentthe user's little finger. The rear surface 120 of the holder 104 may bepositioned in the user's palm, and the user's fingers may wrap aroundthe perimeter edge 105 toward the front surface 108 of the holder 104.When held in a user's left hand, the vertex 107 a may be positionedbetween the user's thumb and forefinger, the vertex 107 c may beadjacent the user's little finger, and the user's remaining fingers maybe adjacent the vertex 107 b.

The optional recessed nature of the control unit 102 within the holder104 may increase the difficulty of removing the control unit 102 fromthe holder 104. With reference to FIGS. 1, 3, and 8-11, the holder 104may include an access, engagement, or removal feature 114 to facilitateremoval of the recessed control unit 102 from the holder 104. The accessfeature 114 may be defined in the front surface 108 of the holder 104.The access feature 114 may be formed as a recessed area 116 that extendsat least partially along a periphery or portion of the control unit 102and the cavity 106. In some embodiments, the recessed area 116 extendsaround the entire periphery of the control unit 102 and the cavity 106.The recessed area 116 may be defined by a recessed surface 118 thatextends around the entire periphery of the control unit 102 and thecavity 106. The recessed surface 118 may extend rearwardly from the rim112 towards a rear surface 120 of the holder 104, and may extendinwardly from the rim 112 towards side walls 122, 124 of the cavity 106and the control unit 102, respectively. The recessed surface 118 may beformed as a chamfer, a cove, a rabbeting, a round over, or othersuitable recessed profiles to facilitate removal of the control unit 102from the holder 104.

With reference to FIGS. 1, 3, 8, and 11, the recessed area 116 mayinclude an accessibility enhancing feature such as a deepened portion ornotch 126 that extends along a portion of the control unit 102 and thecavity 106. The notch 126 may be defined in the recessed surface 118 andmay extend towards and through the side wall 122 of the cavity 106 (seeFIG. 11). The notch 126 may be deepest in a central region thereof, andtapered at the ends thereof. The central region of the notch 126 mayextend through the side wall 122 of the cavity 106, and the ends of thenotch 126 may smoothly transition into the recessed surface 118. Thenotch 126 may provide additional space between the control unit 102 andthe holder 104 to facilitate removal of the control unit 102 from theholder 104 as described in further detail below.

Referring to FIGS. 3-7, the user interface 110 of the control unit 102may be positioned along a front side of the control unit 102. The userinterface 110 may include one or more interactive features 128 (such asone or more depressible buttons, touch screen surfaces, or othersuitable interactive features). The interactive features 128 may includea centrally-located interactive feature 130, and one or more outer ringsof interactive features arranged concentrically around thecentrally-located feature 130. In some embodiments, the control unit 102includes a ring of interactive features 132 arranged concentricallyaround the centrally-located interactive feature 130 and a curvedsegment of interactive features 134 arranged concentrically around thecentrally-located interactive feature 130 and the ring of interactivefeatures 132. The curved segment of interactive features 134 may bearranged along an outer peripheral portion of the user interface 110 andmay, in conjunction with a portion of the unit intended for use inextracting the unit from the holder, surround the ring of interactivefeatures 132 and the centrally-located interactive feature 130.

In some embodiments, an engagement feature 136 is positioned betweenterminal ends of the curved segment of interactive features 134. Theengagement feature 136 may be formed as a curved segment defined by thesame or substantially the same radius as the curved segment ofinteractive features 134, and may be substantially indistinguishable inappearance from the curved segment of interactive features 134. In someembodiments, the engagement feature 136 is fixedly attached to a housing138 of the control unit 102 such that the engagement feature 136 is notmovable relative to the housing 138. In some embodiments, the engagementfeature 136 is inoperable to control an electronic device and is notassociated with any electronic circuitry housed within the control unit102. In some embodiments, the engagement feature 136 is formed as adummy, inoperable, or non-functional button that is fixed to the housing138.

Referring to FIGS. 4-6, the curved segment of interactive features 134and the engagement feature 136 may be spaced forwardly of the side wall124 of the control unit 102 and define a gap 139 between the interactivefeatures 134 and engagement feature 136 and a front surface 142 of theside wall 124. The gap 139 may permit a user to depress one or more ofthe interactive features 134 and cause the one or more interactivefeatures 134 to move toward the housing 138. Movement of the one or moreinteractive features 134 toward the housing 138 may cause the controlunit 102 to generate a control signal and transmit the control signalfrom the control unit 102 to an associated electronic device to controlthe operation of the electronic device. The interactive features 134 maybe formed as depressible buttons biased toward a non-depressed positionand may move into the non-depressed position when not acted upon by anexternal force sufficient to overcome the bias. The gap 139 between theinteractive features 134 and the side wall 124 and between theengagement feature 136 and the side wall 124 may be the same so that theinteractive features 134 are substantially flush or coplanar with theengagement feature 136. In some embodiments, the peripheral edge of theinteractive features 128 may be substantially aligned with an outersurface of the side wall 124 as illustrated in FIG. 6. In someembodiments, as illustrated in FIG. 20, the side wall 124 may surroundthe peripheral edge 143 of the interactive features 128 to inhibit theperipheral edge 143 of the interactive features 128 from being caught orsnagged on another object. As shown in the illustrative embodiment ofFIG. 20, the front surface 142 of the side wall 124 may be substantiallyflush with a front surface of the interactive buttons 128. In someembodiments, the peripheral edge 143 of the interactive features 128 maybe recessed relative to the side wall 124 to protect the interactivefeatures 128.

Referring to FIGS. 4-6, the control unit 102 may include a removalfeature to facilitate removal of the control unit 102 from the holder104. The removal feature may include the engagement feature 136, the gap139 defined between the engagement feature 136 and the front surface 142of the side wall 124, or both. Referring to FIGS. 1 and 15, theengagement feature 136 may be aligned with the notch 126 to facilitateremoval of the control unit 102 from the holder 104 when the controlunit 102 is seated in the cavity 106 of the holder 104. The alignment ofthe engagement feature 136 with the notch 126 may provide the user withadditional space around a portion of the periphery of the control unit102 to remove the control unit 102 from the holder 104 as described infurther detail below. The engagement feature 136 may be configured towithstand the force required to pry the control unit 102 from the holder104.

Referring still to FIGS. 4-6, the engagement feature 136 may define arecess 140 that enlarges the gap 139 between the front surface 142 ofthe side wall 124 and a rear surface 144 of the engagement feature 136to facilitate removal of the control unit 102 from the holder 104. Asshown in FIG. 6, a portion of the rear surface 144 of the engagementfeature 136 may be angled away from the front surface 142 of the sidewall 124 as the rear surface 144 extends towards an outer edge of theengagement feature 136 to define the recess 140 and thereby to enlargean entrance of the gap 139. The recess 140 may ease insertion of auser's fingertip or tool behind the rear surface 144 of the engagementfeature 136 to facilitate removal of the control unit 102 from theholder 104.
